I don't know you personally so I couldn't say, but from your posts you don't seem conceited or arrogant.
Out of all the creators on this site, you are one of the best. I don't know if you feel some sort of pride in that fact, but I feel that you should
If you flaunted that around too much, some people may feel that you're "conceited or arrogant" or whatever; but you don't. You are pretty level headed and take criticism very well. Though, there hardly ever seems to be a reason to criticize your stuff most times
Personally, I'd like to know what the purpose of your poll is. If you want to know how everyone views you in your position, then I guess that'd work. Although, you don't seem to be the type to do that kind of thing. Eh, what do I know anyway. Like I said, I don't know you personally.
Anyway, like most people will probably say, no your not arrogant or conceited but you're the king and you can show off if you want to.
EDIT: *looks at Mewtwo2000's poll* >.> Oh, well then... never mind
